TECHNICAL APPENDIX

DETERMINING THE CABLE SECTION REQUIRED FORLOW-VOLTAGE SUBMERSIBLE MOTORS

The section required depends on the maximum admissible load current - which determines the heating factor - onthe ambient temperature and how the cable is laid.Voltage loss, and therefore loss of cable efficiency, constitutes the decisive selection criterium for long cables.

The required cable section is calculated based on the following formulas:

Direct start: q = Star – Delta start q =

q... cable section in mm2 l... Cable length in mm

l... rated motor current in A cos�... Power factor of submersible motorX... Electrical conductivity (53 for copper) U... Rated voltage∆u Voltage drop in %

When sizing the cable section, keep in mind that higher voltage drops mean increased power losses andconsequently higher operating costs.

The diagrams show how the required cable section is calculated based on a voltage rating of 400V and a power

factor cos�=0,85 and 3% voltage drop, , at an ambient temperature of 30°C. If the temperature is higher than30°C, the maximum admissible current carrying capacity of the cable at the actual ambient temperature must betaken into account (see table next to diagrams).The inductive voltage drop is negligible and has not been taken into account, therefore these diagrams can beadopted regardless of the frequency.The current carrying capacity can be established from the horizontal lines above the length of the cable (verticallines). The bend point indicates the limit length for 3% voltage drops.

Examples:

1.) Star-Delta start:Calculate the cable section Waterproof cableRated motor current: 85 A Length of cable: 35 m

On the horizontal axis, follow the 85 A rated current until you reach a conductivity section with which thelength of the cable is greater than or equal to 35m. In this case, 6 mm2. The maximum length for a 3% voltagedrop is 43 m. Therefore, in this case the voltage drop is 3x35/46=2.3%

2.) the same data, but with 50°C ambient temperature:The table next to the diagram shows that the maximum current carrying capacity of a 6 mm2 cable at 50°C is78 A, therefore a section of 10 mm2 must be selected. The maximum length for a 3% voltage drop is 76 m.Therefore, in this case the voltage drop is 3x35/76=1.4%

3.) the same data, but with 500V voltage:In order to use the diagrams, the rated current of the motor must be converted in proportion to the voltage:

Current reading = 400V x rated current Current reading = 400V x 85 = 68 Arated voltage 500V

The maximum length for a 3% voltage drop is 38 m. Therefore, the voltage drop is: 3x35/38=2.75%

CALCULATING THE SPEED OF THE FLUID THAT FLOWSAROUND A SUBMERGED MOTOR AND SIZING OF THECOOLING SLEEVE

The following formula is used to verify whether the speed of the fluid that flows around the motor of a submersible pump ishigh enough to guarantee the proper cooling of the motor:

Where: Q in [m3/s] is the operating flow rate of the electric pump; only half of this flow is taken into account, because the fluid,which is sucked into the area of the filter (2), comes from the motor side (3) as well as from the pump side (1);D in [m] corresponds to the diameter of the well;d in [m] corresponds to the diameter of the motor (3);v in [m/s] is the calculated speed of the fluid that flows around the motor.

Now, compare the speed thus calculated (v) with the minimum speed required for correct cooling of the motor (vm): if v > vmit means that the motor is properly cooled, if v < vm will be necessary to mount a cooling sleeve (4).

Example:An electric pump OZ630/12 (motor diameter d = 0.144m) operates in an 8” well (well diameter D = 0.203 m) with flow rateQ = 20 m3/h = 0.0055 m3/s.Speed of fluid v = (0.0055/2) / {π·[(0.203)2/4-(0.144)2/4]} = 0.17 m/s.The minimum speed required for proper motor cooling is vm=0.20 m/s.Because v < vm, it will be necessary to mount a cooling sleeve.

––––––––––The following formula is used to determine the maximum diameter of a cooling sleeve to be mounted on a submersiblemotor:

Where: Q in [m3/s] is the operating flow rate of the electric pump; the entire flow is taken into account because the fluid comesfrom the motor side (3) onlyD in [m] corresponds to the diameter of the cooling sleeve (4);d in [m] corresponds to the diameter of the motor (3)vm in [m/s] is the minimum speed of the fluid that flows around the motor.

If the electric pump operates at different flow rates, the minimum flow rate must be taken into account for calculating thediameter of the cooling sleeve

Example:A motor coupled to the electric pump OZ615/24 (motor diameter d = 0.144 m), which operates with flow rate Q=15 m3/h =0.0042m3/s, requires a minimum speed of the fluid of vm=0.20 m/s.Cooling sleeve diameter D = {4·[(0.0042/(0.2·π)+(0.144)2/4]}0.5=0.217 m.

In the case of submersible electric pumps with powerabove 10 HP, the modest mass of the rotor causes aslowdown at changeover, so that the initial Star supplyphase is rendered partially useless.In such cases we recommend using impedance panels oran autotransformer.

• Impedances

The motor is started with a voltage which is lower thanthe rated one, and which is obtained by means ofimpedances.The Lowara panels use impedances which cut down to70% the starting voltage.The switch to the rated voltage takes place without anyinterruptions of the power supply.

WATER REQUIREMENTS IN CIVIL USERS

Determination of the water requirement depends on the type of users and contemporaneity factor. The calculationmay be subject to regulations, standards or customs that may vary from country to country. The calculation methodshown below is an example based on practical experience, designed to provide a reference value and not a substi-tute for detailed analytical calculation.

The sum of the water consumption values of each delivery point determines the maximum theoreticalrequirement, which must be reduced according to the contemporaneity coefficient, because in actual factthe delivery points are never used all together.

The table of water requirements in civil users shows the maximum contemporaneity flow-rate valuesbased on the number of apartments and the type of WC for apartments with one bathroom and two bath-rooms. As regards apartments with one bathroom, 7 drawing points have been taken into consideration, while 11points have been considered for apartments with two bathrooms. If the number of drawing points or apartments isdifferent, use the formulas to calculate the requirement.

The requirements of buildings intended for specific uses, such as offices, residential units, hotels, depart-ment stores, nursing homes and so on, are different from those of condominiums, and both their globaldaily water consumption and the maximum contemporaneity flow rate are usually greater. The diagram ofwater requirements for community buildings shows the maximum contemporaneity flow rate of sometypes of communities, for guidance.These requirements must be determined case by case with the utmost accuracy, using analytical calculation methods,according to particular needs and local provisions.

NPSH

The minimum operating values that can be reached atthe pump suction end are limited by the onset ofcavitation.

Cavitation is the formation of vapour-filled cavitieswithin liquids where the pressure is locally reduced to acritical value, or where the local pressure is equal to, orjust below the vapour pressure of the liquid.

The vapour-filled cavities flow with the current andwhen they reach a higher pressure area the vapourcontained in the cavities condenses. The cavities collide,generating pressure waves that are transmitted to thewalls. These, being subjected to stress cycles, graduallybecome deformed and yield due to fatigue. Thisphenomenon, characterized by a metallic noiseproduced by the hammering on the pipe walls, is calledincipient cavitation.

The damage caused by cavitation may be magnified byelectrochemical corrosion and a local rise intemperature due to the plastic deformation of thewalls. The materials that offer the highest resistance toheat and corrosion are alloy steels, especially austeniticsteel. The conditions that trigger cavitation may beassessed by calculating the total net suction head,referred to in technical literature with the acronymNPSH (Net Positive Suction Head).

The NPSH represents the total energy (expressed in m.)of the liquid measured at suction under conditions ofincipient cavitation, excluding the vapour pressure(expressed in m.) that the liquid has at the pump inlet.

To find the static height hz at which to install themachine under safe conditions, the following formulamust be verified:

hp + hz ≥ (NPSHr + 0.5) + hf + hpv ➀

where:hp is the absolute pressure applied to the free liquid

surface in the suction tank, expressed in m. ofliquid; hp is the quotient between the barometricpressure and the specific weight of the liquid.

hz is the suction lift between the pump axis and thefree liquid surface in the suction tank, expressedin m.; hz is negative when the liquid level islower than the pump axis.

hf is the flow resistance in the suction line and itsaccessories, such as: fittings, foot valve, gatevalve, elbows, etc.

hpv is the vapour pressure of the liquid at theoperating temperature, expressed in m. of liquid. hpv is the quotient between the Pv vapourpressure and the liquid's specific weight.

0.5 is the safety factor.

The maximum possible suction head for installationdepends on the value of the atmospheric pressure(i.e. the elevation above sea level at which the pumpis installed) and the temperature of the liquid.

To help the user, with reference to water temperature(4°C) and to the elevation above sea level, thefollowing tables show the drop in hydraulic pressurehead in relation to the elevation above sea level, andthe suction loss in relation to temperature.

Flow resistance is shown in the tables at pages 78-79of this catalogue. To reduce it to a minimum,especially in cases of high suction head (over 4-5 m.)or within the operating limits with high flow rates, werecommend using a suction line having a largerdiameter than that of the pump's suction port.It is always a good idea to position the pump as closeas possible to the liquid to be pumped.

Make the following calculation:

Liquid: water at ∼ 15°C y = 1 kg/dm3

Flow rate required: 30 m3/hHead for required delivery: 43 m.Suction lift: 3.5 m.The selection is an FHE 40-200/75 pump whose NPSHrequired value is, at 30 m3/h, 2.5 m.

For water at 15°C the hpv term is Pv = 0,174 m (0.01701 bar)γ

and hp = Pa = 10,33mγ

The Hf flow resistance in the suction line with footvalves is ∼1.2 m.By substituting the parameters in formula ➀ with thenumeric values above, we have:

10,33 + (-3,5) ≥ (2,5 + 0,5) + 1,2 + 0,17

from which we have: 6.8 > 4.4

The relation is therefore verified.

FLOW RESISTANCE

TABLE OF FLOW RESISTANCE IN BENDS, VALVES ANDGATES

The flow resistance is calculated using the equivalent pipeline length method according to the table below:

The table is valid for the Hazen Williams coefficient C = 100 (cast iron pipework). For steel pipework, multiply thevalues by 1.41. For stainless steel, copper and coated cast iron pipework, multiply the values by 1.85.When the equivalent pipeline length has been determined, the flow resistance is obtained from the tableof flow resistance.The values given are guideline values which are bound to vary slightly according to the model, especially for gatevalves and non-return valves, for which it is a good idea to check the values supplied by the manufacturers.
